If you want to detect virus online with your file, you can use virustotal and upload your exe file to detect
Choose your file which you want to detect => press scan it, you can see the result of files
Another interesting way is you can view your view by mediafire
If your exe file is infected with a virus, you can view the virus icon on mediafire stored, and you can fix it by click to file... That amazing, right? :D
